We don’t totally understand flight

Newton, Einstein, Bernoulli-many great scientists have tried and failed to fully explain flight. Why is it so hard to explain how planes stay in the air?

Don't worry guys, I'll figure it out and get back to you

reality check
051 there is NO air flow, because AIR IS STATIONARY.! as it moves through air, a wing deflects air upwards and downwards. that deflected air attempts to return to 'equilibrium' in the wake of a wing's passage. such movement of air is Not equal to a horizontally oriented flow of air.
103 it is because of simple newtonian (action/reaction) affects; it is an inclined plane moving through air/fluid.!
122 'other air rises' wtf?!?!#?@?! it is FORCE not rising air.!
136 the following facts have been demonstrated experimentally, via the use of moving air/fluid (wind tunnel.)
a wing that has a symmetrical profile makes no 'lift' if the wing is at zero-degrees angle of attack (aoa).
this is so because, under those conditions the affects/forces above and below the wing are 'equal'.
conversely, a wing that has a symmetrical profile And positive aoa will make lift.! see newton above.
lift (a newtonian affect) is a result of a wing having positive aoa (inclined plane); and drag is a 'penalty' that ALWAYS comes with lift.
that drag penalty is from the (relatively greater amount of) Turbulence that occurs above a lift-making wing. turbulent air is less dense. there is, thus, a persistent zone of slightly 'reduced' air pressure above a lift-making wing.
a symmetrical airfoil/profile that is flat at each of its surfaces produces zones of turbulence at/near its leading and trailing edges.
modern profile designs are Optimized/streamlined, so that the amount of turbulence produced in those areas is minimized. d googletranslate
